The following section describes the relationships among Power Spectral Density (PSD), Equivalent Isotropically Radiated Power (EIRP), and channel width.

EIRP = PSD + 10 log (channel width)

For example, with a PSD of 5 dBm/MHz and a channel width of 20 MHz, the EIRP is:

EIRP = 5 dBm/MHz = 10 log (20 MHz) = 5 = 13 =18 dBm

in the following diagrams for illustration purposes only. 320 MHz channels will be added in Wi-Fi 7.
